Finally, a conclusion will be presented. This chapter will highlight several technicalities of the XML based file format. The following chapter will then show how to put these into use. An office document contains content, for example the text of a letter, or the data in a spreadsheet, along with layout information, which describes how the content should look like.
Also part of document is meta information like who edited a document and how it is called, or additional information such as images or embedded objects.
To a user, these are inseparable parts of a single document. But for processing the document, it makes sense to separate them such that they can be read, interpreted and modified independently of each other. To facilitate this, the StarOffice XML file format stores content, layout, meta information, images and embedded objects in separate streams of a ZIP based package file.
The whole file contains the whole document, the individual streams contain the constituent parts of the document. When creating the XML based file format, we tried to gain as much as was possible from related standards.
The very use of XML is one example. The ZIP format we use for packages are in widespread use. For Math, we use MathML.
This allows easy transformation from and into those formats, and also it allows people to quickly understand our format, if they are already familiar with those formats we make use of.
The StarOffice and OpenOffice. In the XML format, these different ways to format a document use the same style-based representation. The direct formatting is automatically converted into automatic styles , which is a style-based formatting equivalent of the direct formatting the user applied to the document.
A primary design goal of the XML format was to represent all structured information contained in an document as XML structures, thus making the document fully accessible to standard XML tools. This way, all layout information appears as a single string to an XSLT processor, making it very hard to process the layout information in any way.
Our XML file format is a properly designed file format, as opposed to a mere XML dump o f core structures with all their implementation details and limitations. The documents are represented in a way which is easy to understand and use, and not in a way which is easy to implement. This allows the format to abstract application peculiarities and therefore the format may also be used by applications other than StarOffice and OpenOffice.
Throughout the development of the format, great care was taken to make sure the file format is easy to process. Also, the idealized representation makes it easier to improve the StarOffice and OpenOffice. The same format is used across all office applications.
Similar concepts in the different applications always use the same XML representation. For example, spreadsheet tables and word processor tables share a common XML representation, even though their implementations and limitations are quite different.
This has great advantages when processing or generating StarOffice files: The same code works for all applications. For example, a single XSLT style sheet can process both spreadsheets and text documents. Arbitrary XML attributes may be attached to style information and will be preserved when editing such a modified file with StarOffice. Because all formatting information is uniformly represented as styles, and because any document content can be formatted using styles, this allows arbitrary information to be attached to any part of the document content.
Further means to add supplemental information, such as allowing complete streams to be part of the packages, may be added. The previous chapter has highlighted several features and mechanisms of our new file format.
This chapter will look at how this helps different groups of users. To the user of StarOffice and OpenOffice. In additional, the user will gain additional benefits as the document processing and additional solutions described in the following chapters become reality. To a user, their own documents are usually valuable resources, into which lots of time and effort has been invested. What happens, if through an error in the used hardware or software used, the documents become corrupted?

I Agree. Free Online sdd converter. SDD Converter. SDD Viewer. SDD Editor. Compare SDD Files. Merge SDD Files. Since I had little time, I settled for it.
The first would contain copies of all and only the files to convert, still ordered in the same folders and subfolders as in the original archive.
Working in this way, I would not damage the original files in case something went wrong. The second folder would store only the converted versions. If I was absolutely sure that all the files had a.
However, I could not exclude that there were misnamed files as well. Luckily, the Linux "file" command analyzes a file and outputs a description of its type. I also saved the file names I wanted -- that is, the parts before the colon of the lines that contained the string above -- in a separate list:. This allowed me to put all those files in a tar archive and extract the content inside the starofficeconversion folder:.
I had to uncheck the text templates box and disable logging, otherwise the Wizard wouldn't continue -- but apart from that, the conversion worked fine. As you can see in Figure B , "Gemelli alla Rucola e Prosciutto Crudo," along with many other family recipes not available anywhere else, are now safe from oblivion. For the record, I had to disable the log file -- otherwise, the Converter macros in that LibreOffice would fail with this error:. Here, instead, are a couple things you should know before trying this at home.
First, the "Composite Document File V2 Document" string is also present in the description of many non-StarOffice files, and they're almost always recognizable by their different extensions.
This is very good, but wherever they end up, the converted copies all belong to the user who launched the Converter.
